Bibliography and index containing 500 coal-related references and a key word listing. 54 pages. Digital PDF download. B-41D
From the Preface:
This bibliography and index includes approximately 500 references to published and generally publicly available information (such as environmental statements, open-file materials, etc.) pertaining to coal deposits and coal-related activities in Colorado issued between January 1, 1972 and December 31, 1977. This new bibliography is designed to supplement the CGS Bulletin 34-A Bibliography, coal resources in Colorado, published in 1972. However, the present Bulletin also includes a number of pre-1972 references that are not listed in Bulletin 34-A. These additional listings, some of which date back to the late 1800s, were located after a thorough search of the CGS Bulletin 37 Bibliography and index of Colorado geology, 1875-1975.
